Immigration-the great unmentioned

Warner, Gillespie draw differences on issues in Va. senate race | WJLA.com--The coverage on TV has not mentioned the big differences in immigration policy in the races that Republicans have managed to make into races. I have been watching the network coverage on CNN and Fox and no one has mentioned the immigration issue as a reason that Republican candidates unexpectedly came from behind. Gillespie was a 'comprehensivist' going in but staked out more of a border security first position in the debates. Scott Brown hammered the issue. Why will no one mention it?
